Description

  The present invention relates to an anhydrous cosmetic composition that can be separated into a plurality of visually distinct liquid phases.

  Oils are usually used in cosmetics, for example, to impart a conditioning effect on the skin or hair or to remove makeup.

  With regard to hair, it is well known that oil imparts softness and shine to the hair. However, the touch feel imparted by the application of oil to the hair may be undesirable. Accordingly, hair cosmetics for hair conditioning are often based on emulsions that typically contain a cationic agent in addition to several conditioning agents such as water and oil. Because of the anionic nature of the hair, some cationic agents are electrochemically adsorbed to the hair and impart flexibility to the hair. Similarly, hair cosmetics for washing hair include emulsions, which contain several surfactants that can be solubilized by incorporating water and sebum on the hair into micelles.

  For the skin, rinse-off skin care oil is often used for the body to provide moisture to the skin. However, they are too fluid and are often difficult to use. In addition, rinse-off skin care oils are not always adequately rinsed off. Furthermore, they are expensive. Similarly, cleansing oils are used to remove eye and face makeup, particularly in Asian countries. However, these cleansing oils are too fluid and in some cases difficult to rinse off and are relatively expensive, so they have similar problems.

  In a typical cosmetic for hair and skin, at least one oil as a conditioner is combined with at least one surfactant as an emulsifier or detergent and a polar phase such as water. This combination often results in an emulsion having a classic appearance and texture, such as white and creamy.

  On the other hand, there is a need to visually stimulate potential consumers.
